BOAT.

Specification of Letters Patent.

Patented Apr. 22, 1919.

Application 41106 August 31, 1918. Serial No. 252,277.

To all whom it may concern:

Be it known that 1, .AiDJUmR Lamas Pmmenn 'laLBo'r, a subject of theiflinglof Gcreat Britain, ;residing at Montreal, Glillfldll, haveinvented certain new and .usefirzl ments in Boats, of which thefolzlowing is a specification.

This invention relates to improvements in boats; and its object, brieflystated, is the provision olf a boat which is-ufl3inkmh1e.ean =1f filledwith water, and which, by mason'oi its peculiar construction, ispractically incapable of being upset, the invention fiunther aiming toprovide a boat o f the e specified, the speed of which is in no myretarded by the presence esf the aforesaid improvements. I

An embodiment of the linmtionisnilrlustrated in the accompanying dramingwhere- 1n- Figure 1 is a at; Fig. 2 is a side elevation thcneofpand Fig.3 is a, cross-section on line AA, Fig. 2.

Referring more partieulamiy to the dmwing, 1 indicates the body of theboat'w lfich, as shown, comprises the oppositely-located, vertical sideWalls 2 and 3, and the vertical end walls 2 and 3", the side Walls 2 and3 being connected at suitable intervals by cross-pieces or seats 4.

At each side of the boat, there is provided a specially-constructed airchamber 5 which is located intermediate the ends of the side wall 2 or3. Each chamber has its inner side wall formed by the vertical Wall 2 or3, and has its outer side wall made up of oppositely-slanting upper andlower sections 5 and 5 which are connected by a vertical orperpendicular intermediate section 5 disposed parallel with the sidewall 2 or 3. The lower section 5 of this specially-formed outer wall issecured at its bottom edge to the corresponding edge of the adjacentvertical side wall, in some suitable manner, and extends upwardly andoutwardly away from such wall, its upper or top edge joining the loweredge of the connecting section 5 The upper section 5 has its top edgeabutting against and secured to the upper edge of the said side wall 2or 3, and is inclined downwardly and outwardly with respect thereto. itsbottom edge joinln the top edge of the connected section 5 he end wallsof the chambers 5 are formed by substanplan view of the improved tiallyll-shaped parts 5' members 5 boat.

provided on the which constitute the ends of the The opposite side wallsof these memlbers 5" converge sharply, as shown, thereby giving the boata pointed shape at both how and stern to facilitate its progress throughthe water; and said walls are extended rear- Wardly in the planes inwhich they respectively lie to form the parts 5*, which latter betweenand are suitably fixed to the adjacent edges of the sections of theouter walls of the air chambers 55, so that each chamber has the generalshape of a truncarted, quadrangular prism.

The bow and stern members 5 project an appreciable distance beyond theends of the body l of the boat, as well as beyond the air chamber 5,and, by reason of their sharplysaid chambers.

It is to be observed that the air chambers are symmetricallyconstructedand arm ed With respect to the boat, and that their wi th isgreatcst at their central portions, the lower sections 5 of their outerside walls being submerged when the boat is in the water, as will beapparent from Fig. 3, wherein the broken horizontal line indicates thewater level. Consequently, the greatest content of air in the chambersis located approximately at the water level, so that the boat is therebygiven the maximum degree of buoyancy, and is rendered virtuallyincapable of upsetting, or of being sunk. irrespective of the amount ofwater which it has shipped. All of the various joints above describedare water tight, as will be understood.

The propelling mechanism preferably consists of a plurality of paddles 9arranged in pairs at opposite sides of the boat and increasing in widthfrom their inner or upper ends to their free outer ends. rigidlyfastened at their upper ends in some suitable manner in loops 7 formedadjacent one end of a. set of rods 7. one of such rods being providedfor (Zlt'll paddle. (he latter and the rods being disposed at. rightangles to each other. These rods T are pivolally mounted intcrnndiatctheir ends in pairs of perforated brackets 6 which are secured along theupper edges of the walls 2 and 3; and said rods have their inner endsbent They are llO to form handles 8, and their outer ends turnedupwardly. The paddles are shaped or curved in such a manner as to fallat practically a vertical angle over the outer sides of the air chambers5, as illustrated in Fig. 3.

claim as my invention: 1. A boat comprising a body having vertical sideand end walls and a flat bottom; a air of air chambers arrangedsymmetrically on opposite sides of said body and having their innerwalls formed by the adjacent side walls of the body; and V-shaped bowand stern members arranged in front and in rear of the correspondingends of said body and having extensions which form the end walls of theair chambers and serve to close the same.

2. In a boat, the combination of a body having vertical side and endwalls; and a pair of air chambers arranged symmetrically on oppositesides of said bod and having their inner walls formed by t e adjacentside walls of the body, the outer wall of each chamber comprising anupwardly and outwardly inclined lower section socured along its bottomedge to the bottom edge of the corresponding side wall of the body, adownwardly and outwardly inclined upper section secured along its topedge to the top edge' of said side wall, and an intermediate verticalsection secured along its top and bottom edges, respectively, of thecopies at this patent may 12th day of June,

upper and lower sections, and means for closing the ends of saidchambers.

3. In a boat, the combination of a body having vertical. side and endwalls; a pair of air chambers arranged symmetrically on opposite sidesof said body and having their inner walls formed by the adjacent sidewalls of the body, the outer wall of each chamber comprising an upwardlyand outwardly inclined lower section secured along its bottom edge tothe bottom edge of the corresponding side wall of the body, a downwardlyand outwardly inclined upper section secured along its top edge to thetop edge of the said side wall, and an intermediate vertical sectionsecured along its top and bottom edges, respectively, of the upper anlower sections; and V-shaped bow and stern members arranged in front andin rear of the corresponding ends of said body, each side wall of saidmembers having a V- shaped extension which fits between and is securedto the adjacent end edges of the said sections of the outer wall of thecorresponding air chamber so as to close the latter at such end.
